Have you ever hesitated over a property purchase due to the long-term commitment of taking on a mortgage? What if your investments could do the heavy lifting for you?
How an Investment Can Pay Your Mortgage

Let’s take a simple example. Imagine you want to buy a property valued at €400,000 but would prefer not to use your cash savings for the purchase. With a 30% deposit, you secure a mortgage of €280,000 over 20 years at a fixed interest rate of 3.5%. This results in monthly repayments of approximately €1,206.
You then invest a lump sum of €450,000 into a tax-efficient, Spanish compliant investment bond. Assuming an average long-term annual return of 5%, the investment could generate €22,500 in gross income per year.
After taxes, and recognising the tax-efficiency of the Spanish compliant bond, this income is sufficient to cover the monthly mortgage payments. This strategy allows you to keep your capital invested, potentially growing over time, while the income pays the mortgage. Essentially, your investments are working for you—generating returns that fund your property purchase without depleting your savings.

Moreover, using investments in this way can be part of a broader wealth planning strategy.
Some investment bonds offer valuable estate planning advantages, allowing for seamless transfer to beneficiaries, often with no or low tax exposure.
Of course, investment returns are not guaranteed, and it’s essential to regularly review your portfolio to ensure it aligns with your goals and risk tolerance.
Working with an experienced financial adviser can help structure the right investment and drawdown strategy.
Using an investment to pay your mortgage isn’t just possible— with careful planning it can be a workable solution for preserving capital, generating income, and building long-term financial security, all while enjoying your new home.
